Shazam!

My brother bought a Nokia X3-02 recently, and he was going through the Nokia Ovi Store, and found an interesting app,called Shazam (www.shazam.com) they've got apps for mobiles and the pc. it's an online service, which can by listening to any song clip or part of a song, identify it and give you the song details.

The wiki article http://en.wikipedia.org/wiki/Shazam_(service) makes for interesting reading. Apparently there's something known as acoustic fingerprints for audio files.

Cisco 887 and VPN

I'm setting up a Cisco 887 ISR where the internet facing interface is ADSL and this router is the main router for the LAN


Configure the Easy VPN server using Cisco Configuration Professional
1.Create a Loopback interface with IP address 10.10.10.10
2. Configure a Group Name along with a Pre-Shared Key.
3. I'm using a local user database for authentication by enabling AAA logins, so the user authentication is taken care of by the router.
for those who want to configure domain authentication, here's a link a found, but haven't tried yet.

4. Setup an IP range in your network which is not under the common DHCP pool for your vpn clients


I was facing a problem with getting a VPN client for this setup, because my CCO login doesnt have a technical agreement attached to it, and I couldn't find any pointers as to how i can add it.

So I googled and found a few links where I could download it from
http://helpdesk.ugent.be/vpn/en/akkoord.php

But this VPN client could only be installed on 32 bit systems, except for the AnyConnect client , but that supports only SSL connections, for which I would have to purchase individual user licenses.

One option to install the 32 bit client on a 64 bit Windows 7 system , was to run the client in XP mode, and then do a NAT to the host computer. A little complicated but, apparently it works!

After some more googling, I found that Cisco did release a 64 bit VPN client , even though it was in beta.

I'm sorry that I'm not able to paste the link for this client, because when I looked for the download link now, it's been taken offline. I tried to find it again, but all I could find were torrents. They should work too, but I haven't tried them.

The version number for this client is Cisco VPN Client 5.0.07.0290 x64

Once the client is running, you can configure the connection by giving your group name as Name and the Pre-Shared Key as your password.

Once the router has connected, you will be asked for your user login. This is where the user database comes in.

Once you put in the correct user details, you're logged in!
